-LRB- CNN -RRB- -- More than eight years after a Utah teenager disappeared from her bedroom on a summer night , the man authorities believe masterminded her kidnapping is set to stand trial in federal court .

Brian David Mitchell , 57 , is accused of snatching then-14-year-old Elizabeth Smart at knifepoint from her family 's Salt Lake City home on June 5 , 2002 -- a crime that shocked the nation and the city , which was then basking in the glow of the 2002 Olympic Winter Games a few months earlier .

Mitchell faces federal charges of kidnapping and transporting a minor across state lines for improper purposes . Jury selection in his trial is scheduled to begin Monday in Salt Lake City .

In the months that followed Smart 's disappearance , her anguished parents , Ed and Lois , became a familiar sight in the media as they continued to plead for their daughter 's safe return .

But no one expected what happened in March 2003 , when Smart was found walking down a street in the Salt Lake City suburb of Sandy in the company of Mitchell and his wife , Wanda Eileen Barzee . Mitchell , a drifter and self-described prophet who called himself `` Emmanuel , '' had done some handyman work at the Smarts ' home .

Utah prosecutors charged Mitchell with six felony charges of kidnapping , sexual assault and burglary . But in July 2005 , a Utah district court judge ruled him incompetent to stand trial , leaving him in custody at the Utah State Hospital .

However , the state case against Mitchell was put on hold when federal authorities stepped in . A grand jury in 2008 indicted Mitchell and Barzee . U.S. District Judge Dale Kimball found Mitchell competent to stand trial in March .

Barzee , 64 , pleaded guilty in November 2009 to kidnapping and unlawful transportation of a minor in federal court and was sentenced in May to 15 years in federal prison . She also pleaded guilty but mentally ill in state court to conspiracy to commit aggravated kidnapping in an attempt to kidnap Smart 's cousin a month after Smart was kidnapped . She was given a sentence of one to 15 years , to be served concurrently with the federal sentence , and given credit for the seven years she had spent in custody .

As part of her plea agreement , Barzee agreed to cooperate in the state and federal cases against her husband . However , her name does not appear on a witness list filed by federal prosecutors -- and does appear on a list of witnesses filed by the defense .

Smart , her mother and her younger sister , Mary Katherine -- who was sleeping in the room with Smart the night of the kidnapping and was the only witness -- all appear on the prosecution 's witness list .

Mitchell 's attorneys attempted to move his trial , saying it should be held outside of Utah because publicity in the case had prejudiced the pool of potential jurors against him and jeopardized his right to a fair trial .

Kimball denied that request in August , and defense attorneys appealed his ruling to the 10th U.S. Circuit Court of Appeals in Denver , Colorado . A three-judge panel on the appeals court denied the request last week , saying it was premature since jury selection had not taken place .

`` It is possible that a jury could be seated where all the jurors would satisfy Mr. Mitchell 's view of impartiality , '' the 10th Circuit ruling said .

Defense attorneys in July said in court documents that they intend to utilize an insanity defense and intend to introduce expert testimony relating to an alleged mental disease or defect .

Now 22 , Smart testified as part of Mitchell 's competency hearing last year that after taking her -- still dressed in her red pajamas -- from her home , Mitchell took her to a wooded area behind her home and performed a mock marriage ceremony with her before sexually assaulting her . She testified he repeatedly assaulted her during her months in captivity , and that he and Barzee took her to California before returning with her to Utah .

The federal court summoned 600 jurors to fill out a preliminary juror questionnaire in the case , according to court documents . About 500 potential jurors attended the sessions on September 30 and October 1 . Some were released on hardship grounds , the documents said , but about 330 jurors completed the questionnaire .

Kimball narrowed that number down to slightly more than 200 potential jurors , according to The Salt Lake Tribune newspaper .
